The Style Guide moved into the Documentation site for better visibility. Removed lots of discussion around topics that are already enforced by the formatter/linter. Added new advice regarding a variety of topics.
The Test Writing Guide discusses how to write tests for Flame, and what kinds of tests are available.
Additional mode "infobox" allows Flutter widgets to be inserted into the generated documentation site as wikipedia-style infoboxes floating on the right. This is useful for presenting content to the user up-front without sacrificing the flow of the exposition. For example, currently the Tap Events demo is "hidden" in the middle of a long page.
We believe that presenting the content in this way would make the user more excited to read about it.
